The Steel Wood Manor contains steel trees that grows on special dark soil and produces Steel Wood. This enterprise for the Lin Family would increase the profits for each year by approximately forty percent. Steel Wood was produced here in abundance and this type of Steel Wood was just like quality steel. It was resistant to both water and fire plus it was thick and strong, extremely suited for manufacturing weapons and construction purposes. Thus, this type of Steel Wood was relatively highly priced, combined with the fact that the Steel Wood Manor was the only source of Steel Wood within a 50 kilometer radius.
Yang Yuan Stone
The Steel Wood Manor contains a Yang Yuan Stone lode. It is said that a lode, even a small one dwarfs the Steel Wood enterprise.
Later a tunnel was found that led to a crevice. The air in the crevice contains Yang Energy. The crevice is a blazing red-hot rocky area. When found a pile of tens of feet high white beast bones lied in the centre of the room. It is deduced that the bones are from a very powerful Demonic Beast.
A long time ago, the area where the Steel Wood Manor is presently located, was a volcano and all the dark soil came from when the volcano erupted. Now that the volcano has vanished, the dark soil is a limited commodity.
It was a significant enterprise in the Lei Family.
Lei Bao wagered the Steel Wood Manor for one of the Fire Python Tigers Lin Dong had. He did this because he thought Lei Li would win the duel with Lin Dong. However to everyone's surprise the latter won. Lin Zhentian tells Lei Bao to give the Lin Family the Steel Wood Manor within half a month. The Lei Family however wasn't planning to give the Lin Family the Steel Wood Manor so easily. They shopped down the trees as much as possible and also poisoned the ground so no trees could grow.
Later Lin Dong and Qing Tan found a Yang Yuan Stone. This led to the discovery of the existence of a Yang Yuan Stone lode. This discovery made that the Lin Family has now more resources.
When mining a worker from the Lin Family found a tunnel. This led to a crevice filled with Yang Energy.
